WOVEN-wins FABRIC.

SPECIFICATION forming part of Letters Patent No. 545,964, dated September 10, 1895.

Application filed January 24, 1895. Serial No. 536,012. (No model.)

To @ZZ whom it' may concern:

Be it known that I, MARSHALL B. LLOYD, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Im provements in VVovenWire Fabrics, of which the following is a specification.

My invention relates to woven-wire fabrics for use as bed-springs and mats; and the object of the invention is to produce a non-col-v lapsible coiled-wire fabric wherein all the coils run in the same direction.

To this end my invention consists in a coiled-wire fabric composed of two series of helical coils, all running in the same direction, and said coils abutting and interlocking to constitute a woven fabric, which, owing to the abutment of the several coils, will not collapse under lateral pressure.

In the accompanying drawings, forming part of this specification, Figure l is a plan view of a part of a fabric constructed in accordance with my invention. Fig. 2 is a transverse section on the lines a; of Fig. 1. Fig. 3 is a diagonal side view of a piece of fabric.

The fabric may be described as consisting of two series of wires formed into similar helical coils and all running in the same direction, the wires of one series alternating in longitudinal position in the wires of the other seriesand both series of wires interlooked both with the wiresof the same series and with 'the wires of the other series, but abutting therewith, Owing to their different longitudinal positions.

In the drawings, A. represents the wires of one series, which I term the first series, and B represents the wires of the other or second series; but this designation of first and second is purely arbitrary, as either series may be correctly called the first or the second The wires are formed into helical coils, and the wires of one series alternate with the wires of the other series, and also interlock with'the other wires of the same series and with those of the other series. In forming the fabric I preferably make, first, a coiledwire fabric of ordinary construction. Then I move all the wires bodily longitudinally (without rotating them) as far as they will go. This brings the extreme portions ofthe spirals in contact with one another. I then intercoil the wires of the second or B series. These wires run in the same direction as the A series, but they alternate therewith in lon gitudinal position, each wire of the second or B series interlocking with these wires ofI the first or A series and with two other wires of its own or the B series. It will be seen, also, that there are a Series of diagonal ridges with interposed valleys extending across the fabric on either side thereof, the ridges being formed by the highest portions of the coils, first of one series, then of the Other-that it to say, one ridge is formed by the highest portions of the coils of the A series and the next by the highest portions of the coils of the B series. This feature of the fabric adapts it especially for use as counter or change mats,

as coins placed on the mat in an upright. position will stand upright between the ridges, thus being held in a convenient position for being picked up.

I do not confine myself to the described manner of making the fabric, as I may make it by adding a wire first of one series, then one of the other, to the edge of the fabric.

In order that the construction of the fabric may be thoroughly understood, I will describe the same in another manner.. The fabric maybe said to be made up of a number of pairs of helical coils, all running in the same direction, and the coils in each pair being concentric or having a common axis, and for the sake of description the numerous pairs of coils may be said to be divided into two series, the first series being made up of a number of such pairs of concentric coils arranged side by side and abutting one another, and the second series composed of'a number of similar coils, the pairs of which abut against one another and interlock with the coils of the first series and are themselves interlocked by the first-series coils. The arrangement of the coils may be clearly understood by comparing the same with a number of intersecting circles. It is obvious that instead of pairs of coils sets of more than two concenn tric coils might be employed in making up the fabric; or in place of the foregoing description of my fabric the same may be described as consisting in a series or number of pairs or IOO sets of concentric coils, which pairs or sets interlock with one another in succession and alternate pairs abutting one another within the intermediate pair of coils.

By this manner of interlocking the wires every wire is locked in both directions against lateral movement. I am also able to produce with fine wires and with less weight of wire to the square foot a stronger, more durable, and better fabric than can be produced in the ordinary way with coarser and heavier wire.

The ordinary fabric when not secured to a frame or otherwise held has a tendency to collapse laterally, such collapsing being produced by several adjoining or adjacent wires moving laterally, so as to be brought into the same cylindrical space. This, however, is absolutely prevented by my construction, as the crossing of the Wires at the points where they come together precludes any lateral movement of any of the series.

The fabric is adapted for fine bed-bottoms, for Hoor-mats, counter-mats, table-mats, and many other uses.

Having thus described my invention, I claim as new, and desire to secure by Letters Patentl. The coiled wire fabric, consisting of a series of helical coils interlocked with one an.- other, and a second series interlocked With one another and with the first series, all of said coils running in the same direction, and the coils of one series alternatingin longitudinal position with the coils of the other series, substantially as described.

2. A coiled wire fabric consisting of pairs or sets of concentric coils, said pairs or sets interlocking one another successively, and alternate pairs abutting one another within intermediate pairs or sets, substantially as described.

3. In a coiled wire fabric, the combination, of a series of interlocking pairs or sets of concentric coils, each of said pairs or sets being made up of coils varied in longitudinal position, and alternate pairs abutting one another Within intermediate pairs or sets, Whereby the fabric is rendered non-collapsible under lateral pressure.

4. A coiled wire fabric, consisting of two series of coils all running in the same direction, each series being made up of abutting pairs or sets of concentric coils, the pairs of each series interlocking those of the other series, substantially as described.

5. A woven-wire fabric, consisting of a series of helical coils, all running in the same direction, said coils interlocking and abutting to form a non-collapsible fabric, substantially as described.

6. As a new article of manufacture, a laterally non collapsible fabricv comprising a number of helical coils of wire, all coiled and running in the same direction and interlock-y ing successively, substantially as described.

In testimony whereof I have hereunto set my hand this 17th day of December, A. D.
